IOST OR STAKE FULLER.

Application filed November 3, 1927. Serial No. 230,788.

This invention relates to certain new and useful improvements in post orstake pullers, and it has for its object, among others, to provide asimple, efficient, strong and durable device for quickly and easilyextracting a post, stake, pipe, or any other device from the ground orother place where 1t be located. It will befound useful in lift ng apipe from an oil well or lifting or raising any element by which lt'maybe caused to grasp.

The invention has for an obJect, among others, to provide a post orstake puller, of a portable nature, capable of being set up in thedesired position and readily applied to the post or rod, the latterbeing readily lifted and a new grip automatically obtained thereuponafter each raising of the post or rod.

It has for a further object to provide a device of this character,quickly adjustable for use upon posts, rods or the like of differentdiameter and of any cross SGC-tlOIL,

The device embodies two parts, both capable of being manufactured atsmall cost,

possessing greatstrength, and not requiring skilled labor to apply ormanipulate the same.

Other objects and advantages of thelnvention will. hereinafter appearand the novel features thereof willbe particularly out in the appendedclaims.

The invention, in its preferred form, is clearly illustrated in theaccompanying drawing, which with the numerals of reference. markedthereon, form a part of this specification, and in which,

Fig. 1 is a front view showing the device applied to a rod.

Fig. 2 is a side elevation of the same, showing the operating lever andthe gripping means in full and dotted line positions.

Fig. 3 is a top plan view of Fig. 2.

Fig. 4 is an enlarged top plan'view with the operating handle broken 01fshowing the chain-holding member, which latter serves a furtherfunction, soon to be described.

Fig. 5 is a side elevation of the chain-holding member, the operatinghandle being broken away.

Fig. 6 is a face view of the chain-holdinn member, and

Fig. 7 is a side elevation with a portion in broken lines, showing amodified construction. 7

pointed new Like numerals pertain to like parts throughout the generalviews.

Referring to the drawings, 1 designates the upright or supporting memberwhich I may vary in the form and construction, butin the presentinvention shown as being of substantial form, the base 2 of which isdesigned to rest upon the ground or other support, the side members attheirupper end being drawn parallel to each other and extended slightlyabove their bend to form the flanges 3 between which is mounted uponasuitable pivot 4,'an operating handle" 5.v

As seen in Figs. 2 and 5, the operating lever 5is extended beyond itspivot to form a short arm 6 to the free end of which is pivotallymounted the member 7. The construction and character of this member 7will be best understood by reference to Figsia, 5 and 6,

in which it is shown as a combined dog and chain-receiving member, thesame having the spaced-apart'jaws or the like 38'( see Fig. 4), betweenwhich is pivoted upon the pivot pin a) the 2nd of the short arm 6 of theoperating ever The member .7 is formed upon opposite sides of theportion 8 with lugs or ribs 10 see Figs. 4, 5 and 7) to add strength tothe same, and what may be termed the forward end of this member, isprovidedwith the substantially \l-shaped notch 11 and intermedi ate saidnotch and the rear end of such memher, are openings 12 a1l of which willbe clearly seen from reference to Fig. 4-.

Theimember 7 is provided with the upwardly extending portions 13, havingopen' ings 14 extending transversely and whichserve for the reception ofa cotter pin 15, as indicated by dotted lines in Fig. 4 and full linesin Fig. 3. In one form of the invention, soon to be described, thecotter pin forms 1 a double function. In the form shown in Figs. 2, 4. 5and 6, it serves to prevent displacement of the chain, while in the formshown in 7, it serves not only this last mentioned function, but alsoserves as the means of pivotal connection between the ends of the shortmember 6 of the lever and the member 7. It is to. be understood that inthis last connection or arrangement, that is, where the cotter pinserves the double purpose above mentioned, the pivot 9 heretoforedescribed as being that upon which the operating lever had pivotalconnection with the member 7, is omitted. Y I I bight of the chaindepending, and the ends of the chain are then passed through the opening 17 in the jaws of the member 7, resting upon the walls 18 tllOlGOll,and the cotter pm 15 is disposed above the chain in said open- 1 ings,the chain being first passed around the post or other object 19 to belifted. V

The full line position of the lever or operating member 5, the member 7and the chain 16,-is that of the parts prior to manipulation of themember 5. lVith the partsin this position the post or rod 19 is looselyreceived within the bightof the chain. As the lever is moved from thefull line position to that shown in dotted lines in Fig. 2, the post orrod is held'in a tight grip between the bight of the chain and theangular walls of the notch 11, and the post or rod is lifted. The arm 5then being again raised from the dotted to full line position, the chainis :automatically released. irom its hold on the member 19 andfalls tothe full line position, when repetition of these 'n'iovementsalternately. gripsand releases the member 19 until it is eventuallypulled from the ground.

lVhen the cotter pin 15 is in position over the chain,'the latter isheld fixedly in adjusted position. If it is desired to grasp a larger orsmaller'post 19 the pin is moved in its bearings'until one end of thechain is disengaged when the same may be moved through its opening inone direction or the other to increaseor decrease the bight oi": thechain.

- In the construction shown in Fig, 7, the operation of the parts-issubstantially the same as in the other form but the pin 15' serves bothas the pivotal connection between the free end or" the short arm 6 ofthe operating member 5, and the portion 13 of the member 7.

his to-be noted that the member? is in both instances gravitatinglymounted upon 'the' arm 5, so as to automatically drop intollOlCllIlg'pOsltlOn' thief the lever is moved.

rModificat-ion in detail may be resorted to Without departing from thespirit of the invent-ion or sacrificing any of its advantages.

IVhat I claim is I 1. In a pulling implement, a member having verticalopenings and a rod-engaging notch and jaws with openings for the reception of a rod-engaging element threaded ing vertical openings, a notchat one end in terspaced with said openings, and passages on the oppositesides 7 or" said openings, and strengthening ribs at said openings, andspaced-apart jaws between said passages.

. .5 A pulling implement comprising-a support, an operating leverpi'votally mounted thereon, a clutch member pivotally carried by saidoperating member and having a notched free end engage the object to bepulled, and a flexible gripping member carried by the clutch membertocooperate with the said notch form a grip onthe said object. 7

6. A pulling implement comprising support, an operating lever pivotallymounted thereon, a clutch member pivotally carried by said operatinglever and having a notched free end to the object to be pulled, and aflexible gripping member carried by the clutch member to cooperate withand acting in opposition to said'notch to form a grip on the saidobject.

7. A pulling implement in accordance with claim 5 in which the clutchmember has openmgs for the passage of said flexible member.

In testimony whereof ture.
